DEAD-box helicase domain of Pif1; Pif1 and other members of this family are RecD-like helicases involved in maintaining genome stability through unwinding double-stranded DNAs (dsDNAs), DNA/RNA hybrids, and G quadruplex (G4) structures. The members of Pif1 helicase subfamily studied so far all appear to contribute to telomere maintenance. Pif1 is a member of the DEAD-like helicases superfamily, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. This domain contains the ATP-binding region.

C-terminal helicase domain of RecD family helicases; RecD is a member of the RecBCD (EC 3.1.11.5, Exonuclease V) complex. It is the alpha chain of the complex and functions as a 3'-5' helicase. The RecBCD enzyme is both a helicase that unwinds, or separates the strands of DNA, and a nuclease that makes single-stranded nicks in DNA. RecD family helicases are DEAD-like helicases belonging to superfamily (SF)1, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. Similar to SF2 helicases, SF1 helicases do not form toroidal structures like SF3-6 helicases. Their helicase core consists of two similar protein domains that resemble the fold of the recombination protein RecA. This model describes the C-terminal domain, also called HelicC.

Ti-type conjugative transfer relaxase TraA; This protein contains domains distinctive of a single strand exonuclease (N-terminus, MobA/MobL, pfam03389) as well as a helicase domain (central region, homologous to the corresponding region of the F-type relaxase TraI, TIGR02760). This protein likely fills the same role as TraI(F), nicking (at the oriT site) and unwinding the coiled plasmid prior to conjugative transfer.

exodeoxyribonuclease V, alpha subunit; This family describes the exodeoxyribonuclease V alpha subunit, RecD. RecD is part of a RecBCD complex. A related family in the Gram-positive bacteria separates in a phylogenetic tree, has an additional N-terminal extension of about 200 residues, and is not supported as a member of a RecBCD complex by neighboring genes. The related family is consequently described by a different model. [DNA metabolism, DNA replication, recombination, and repair]

The AAA+ (ATPases Associated with a wide variety of cellular Activities) superfamily represents an ancient group of ATPases belonging to the ASCE (for additional strand, catalytic E) division of the P-loop NTPase fold. The ASCE division also includes ABC, RecA-like, VirD4-like, PilT-like, and SF1/2 helicases. Members of the AAA+ ATPases function as molecular chaperons, ATPase subunits of proteases, helicases, or nucleic-acid stimulated ATPases. The AAA+ proteins contain several distinct features in addition to the conserved alpha-beta-alpha core domain structure and the Walker A and B motifs of the P-loop NTPases.

(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles

(labeled illustration) Four types of hits can be shown, as available,
for each region on the query sequence:
specific hits meet or exceed a domain-specific e-value threshold
(illustrated example)
and represent a very high confidence that the query sequence belongs to the same protein family as the sequences use to create the domain model
non-specific hits
meet or exceed the RPS-BLAST threshold for statistical significance (default E-value cutoff of 0.01, or an E-value selected by user via the
